[BioC] readFASTA Arguments

[Colleen Doherty]

Hi,
 I am trying to use readFASTA in Biostrings.

As this it works fine:
Tair8upstream<-readFASTA("TAIR8_upstream_500_20080228",strip.descs=FALSE)

I would like to use some of the other arguments - use.descs, width,
and checkComments
However, I get an error when I try this.

> Tair8upstream<-readFASTA("TAIR8_upstream_500_20080228",strip.descs=FALSE, use.descs=TRUE)
Error in readFASTA("TAIR8_upstream_500_20080228", strip.descs = FALSE,  :
  unused argument(s) (use.descs = TRUE)

or

> Tair8upstream<-readFASTA("TAIR8_upstream_500_20080228",strip.descs=FALSE, width = 250)
Error in readFASTA("TAIR8_upstream_500_20080228", strip.descs = FALSE,  :
  unused argument(s) (width = 250)

I didn't see an example with these arguments in the manual, so maybe I
do not have the correct format.
Any suggestions?

sessionInfo is below.

Thanks,
Colleen
